Which parties are required to declare their funding?

They are obliged to declare the parties represented in the Federal Assembly. In 2025, nine out of ten of these parties disclosed their data to the Federal Financial Controller. Only national sections are subject to the obligation of transparency, not cantonal or municipal ones. The declaration includes income from donations, demonstrations, sale of goods and services, contributions from members and legates, but not contributions to parliamentary groups.

Why did the PS collect more revenue than the other parties?

The source does not specify the exact reasons for the financial supremacy of the SP. However, the 2025 data confirms a well-established trend: the PS remains the party with the highest revenue volume, equal to 7.9 million francs, although it has suffered a slight contraction of 0.3 million compared to 2024. The reasons may vary: organisational structure, shareholder base, fundraising capacity or composition of donations.

Why has the Ticinese League not published its data?

The source does not specify why the Ticinese League did not disclose its funding in 2025, despite being one of the ten parties represented in the Federal Assembly. Official data from the Federal Financial Control simply indicate that the party "has not yet disclosed its funding", without providing further clarification on the timing or causes of the delay.

How did overall revenue change between 2024 and 2025?

Total revenue reported by nine federal parties fell by about CHF 1 million: from CHF 25.6 million in 2024 to CHF 24.6 million in 2025. This contraction is mainly due to the decrease in the PLR (-1.8 million), partially offset by the increase in the UDC (+1.0 million). The other parties represented in the Federal Council underwent slight changes: PS (-0.3 million) and Centro (+0.1 million).

What is NOT included in the reported funding data?

Official data exclude contributions to parliamentary groups, which are not subject to the transparency obligation. Furthermore, if parties pay funds through their cantonal or municipal structures (rather than the national section), these amounts will not appear in the federal register. This means that the official figures represent the minimum guaranteed by law, not necessarily the totality of each party's actual funding.

# Political Funding Numbers

The Federal Financial Controller has made public the data on the revenue declared by nine of the ten parties represented in the Federal Assembly for the year 2025. Altogether, the amounts amount to 24.6 million francs, a figure that marks a contraction of about one million compared to the 25.6 million declared in 2024. Leading the national ranking is the Socialist Party (PS) with 7.9 million francs, confirming the party with the highest income ever.

Behind the PS are the Radical Liberal Party (PLR) with 4.8 million, the Centre Democratic Union (UDC) with 3.8 million and the Centre with 2.7 million. The Greens declared 1.8 million francs, while the Liberal Greens stand at 1.2 million. The Remaining Parties — Democratic Union

Operational details

What emerges from the data

The overall contraction of one million francs between 2024 and 2025 deserves attention. If the SP maintained absolute leadership, its loss of 0.3 million suggests a slight erosion in fundraising capacity. More relevant is the decline in the PLR, which lost as much as 1.8 million: the figure represents almost 27 percent of the radical party's overall revenue, signaling a significant reduction in its funding base.

Otherwise, the UDC has been able to increase its revenues by 1.0 million francs, a result that positions it as one of the few winners of this round. The Centre, despite having earned only 0.1 million, has at least confirmed a stability in its cash flows. Among the smaller parties, the situation remains more contained. The Greens, with 1.8 million, remain the third pole after PS and PLR for declared revenue volumes, while the liberal Greens are significantly different with 1.2 million.

The lack of data related to the Ticinese League complicates the national picture: not knowing how much this formation has collected prevents having a complete picture of federal political funding in 2025.

What counts as "revenue"

Importantly, the figures released by the Federal Financial Control do not include all cash flows to parties. Mandatory declarations relate to income from donations, events, sales

Key points

Transparency and access to data

In Switzerland, the obligation to be transparent about party funding is one of the pillars of federal democracy. Parties that have representation in the Federal Assembly must submit their entry data to public scrutiny every year, according to the rules on the transparency of policy funding. This mechanism allows citizens and researchers to verify the economic sources of the main national political actors.

The Federal Financial Control acts as the body responsible for the collection, verification and publication of this data. The annual reports make the totality of declared revenues public, allowing a cross-cutting view of how parties finance themselves. Access to this information is guaranteed: anyone wishing to consult the data can do so through the official channels of the federal administration.

However, as the current data has shown, transparency has structural limitations. Not all political formations with federal representation declare promptly (the case of the Ticinese League demonstrates this), and the possibility for parties to pay funds through their cantonal structures creates grey areas in the overall framework.
